My husband Sean and I have two boys, Mason (10) and Colin (8), and one crazy dog, Finley. I enjoy spending time with my family or friends and relaxing by the lake. We like to be outdoors hiking, swimming, boating, or biking. I am excited to become part of the wonderful group of educators at LCK!

My name is Kelsea Tajnai and this will be my first year as the 3K teacher at LCK. Before becoming a stay at home parent, I worked in several settings of early childhood and am looking forward to returning to the field. I live in Hartland with my husband Jon, son Jack (7), daughters Marni (6) and Ester (4) and our dog Rocky. I love to spend my free time doing all things outdoors with my family, being out on the water, enjoying quality time with friends or getting lost in a good book. All three of our children have gone through the LCK program and last year I had the opportunity to sit on the board as Vice President of Operations. I am excited to now be part of the staff and continue to serve in this phenomenal community.

3K Paraprofessional/Before and After care Aide

My name is Mallory Hazelwood and I am the 3K paraprofessional for LCK. I live in Hartland with my husband Jesse and our three daughters Jordyn (16), Jenna (15), and Jayce (5). Jayce attended LCK for 4K and I often helped in her classroom.  We also have a 9 year old Weimaraner named Kaiser. Before becoming a stay-at-home mom, I spent several years working with young children. I have certifications in both infant and early education. In my free time I enjoy cooking and baking, spending time with family and friends, gardening and traveling to our favorite vacation spot, Folly Beach!

After care Paraprofessional

My name is Patti Dibb and I will be the after care aide for the 3K and 4K morning classes this year.  I live in Merton with my husband, Chad, and our two children; Hannah (10) and Colt (6) who both attend NLS.  Colt attended LCK for 4K.  We share our home with our 2 dogs and 2 cats.  Over the years I have had jobs that have prepared me for this new role.  I spent 12 years as a zookeeper.  One of my responsibilities was to teach children about the animals in my care.  That was always a highlight in my day!  For the past 9 years I have also owned a photography business where I work primarily with young children and families.  I pride myself in being able to make a connection with children quickly during our photo shoots.  Last year I had the pleasure of photographing the 3K and 4K classes and I enjoyed how much the children welcomed me into their classrooms.  Over the past 3 years I have opened my home to childcare for a few families.  I have been a Girl Scout leader for my daughter’s troop since she was a Daisy in Kindergarten.  My husband and I (along with some other awesome parents) coach one of the North Lake Tball teams.  I enjoy being involved with my children’s school as much as possible!  I cannot wait to spend a couple hours a day with some of the 3K and 4K students this coming school year!
